For the feeding valve drive in powder and granular material air transport. A geared motor that achieves both high torque and overwhelming low cost. Supports small batches of several dozen units.
The "air transport system for powders and granules" efficiently conveys resin pellets, food powders, chemical raw materials, and more. Preventing wear and clogging at bends in the piping and reducing maintenance costs is extremely important for the stable operation of the entire plant or factory. In this air transport line, a "rotary valve" or "screw feeder" that smoothly feeds a constant amount of powder into the piping without jamming is essential, driven by a geared motor equipped with "high torque" and "durability" to withstand the strong resistance of the powder. Kuru Co., Ltd. offers the optimal "parallel shaft geared motor (PGM series)" for powder transport equipment's feeding and rotary valves. By utilizing traditional design concepts in a mass production model, we achieve overwhelming low costs. We provide three types of shapes (parallel shaft, L type, R type) that are easy to install in limited spaces, ensuring Japanese quality through domestic inspection of all units, and strongly support equipment manufacturers from small lot prototypes of several dozen units.

basic information
■ The Role of Motors in Powder and Granule Air Transport and Feeding Valves Continuous low-speed, high-torque drive is required to withstand the harsh loads from the weight of the powder and jamming, and to prevent pipe blockages. ■ Features of Kuru's Parallel Shaft Geared Motors (PGM Series) - Three shape variations: In addition to the most standard "Parallel Shaft (S1)," we offer the "L Type (S2: Hollow Shaft Flat)" and "R Type (S3: Orthogonal Shaft)" which are optimal for space-saving and orthogonal arrangements, perfectly fitting into limited spaces around piping. - Wide range of power specifications: Standard lineup includes "DC24V," "AC110V," and "AC220V," accommodating various control and power environments. - High torque & long lifespan: Designed for low noise, long lifespan, and maintenance-free operation, contributing to continuous plant operation. - Quality assurance and support: Customizations such as adding non-excitation brakes are available, and all units undergo domestic inspection from prototypes and small lots to mass production. Dedicated staff will work alongside until technical challenges are resolved.
Price information
By stripping away excessive features and focusing on basic performance, we have achieved an overwhelmingly low price of "less than half" compared to conventional domestic manufacturer equivalent products (brushless motor + planetary gear). The drastic cost reduction of the motor alone dramatically lowers the manufacturing cost of the entire equipment. Prices vary depending on the combination of voltage, output, gear shape, and driver, so please request a detailed estimate. It demonstrates its maximum effectiveness when implemented in bulk for mass production machines (volume discount).

Applications/Examples of results
It is active in various feeding and input mechanisms for powder and bulk material transport and air transport lines. - Rotary valve drive for air transport lines of resin pellets and plastic raw materials. - Drive for powder supply screws for food powders (such as flour, sugar, spices, etc.) and pharmaceutical raw materials. - Power for constant flow input valves in air transport equipment with measures against pipe wear and blockage. - Drive for rotary valves for dust discharge under dust collectors and cyclone separators. - Automatic supply devices for bulk materials in various chemical plants and recycling factories. We support equipment engineers who are troubled by wanting to "reduce the cost of feeding valve motors while choosing shapes that fit their space" with our proposal of "CLUE (a clue to the solution)" and "thoughtful support," taking responsibility until the end. Product lineup: - Parallel axis geared motors (PGM series: S1 parallel axis / S2 hollow shaft L type / S3 orthogonal axis R type) - Various motor drivers (E series / MLD series / BHR series)
